Yes! I know the two "peek&poke" command but at the start of ft8x7 development we decided to go with clone to be safe.

I'm sorry to have no time for a longer answer but I think you can go back in archive and find the original discussion.

In any case I was thinking to make also the "non clone" driver once I'll have completed with all settings support.
I don't really have much spare time but work is going on.
I'm just a little scared that wrong timing or communication errors can lead the radio to write on the wrong area and you know the calibration parameter are there in memory.

BTW I would like to thank you again for your code which is really saving me some programming time.

Presently, Chirp communicates with the Yaesu FT-897D only in clone
mode.  It's been quite some time, but as I recall, one can read/write
memory in the FT-897D (and I think the FT-857 and FT-817 series as well)
using two commands (one for read, and one for write) that provide a
radio memory address ...

Are you planning to make that kind of change to Chirp?  That would be
more convenient for users than going into clone mode. ...
